In all honesty, I don't see why the WC in a small state like Qatar would be an issue. The close proximity of the stadiums will be an advantage to thousands of fans - fly to Doha, watch 6 games in 6 different stadiums (or whatever.) Makes travel arrangements an awful lot easier, if you ask me.
The disadvantage is, of course, that there isn't all that much to see outside of football. But most fans won't be going there for the sightseeing anyway. (And if they do, they can travel the entire Middle East (and then some) if you compare it in size to Australia or the USA.)
